Hi greydog (dave), not runflats on it, pretty budget tyres, got the car from a local dealer and this is our 3rd car from them as they only specialise in high end quality cars, had a Q7 for 5 months just before this X6 and the dealer took it back without any hassle as it had ongoing issues, I do know it's the large staggered wheels but a car like this needs them car is pretty much showroom condition. just the car came into them with these tyres on it and still have about 5-6mm on them however did notice yesterday that the rears are m+s marked but the fronts aren't. Wife hasn't noticed any judder and to be fair I dropped the kids to the bus this morning and car was smooth and perfect and I can't see the dealer saying yep no problem I'll fit £700 worth of new tyres for you 😂 so hopefully these tyres will wear out pretty quickly and I can get something descent on as a car like this deserves them. thanks
